Mental consciousness is in the brain. That's its location. Reality or Mind or life itself has no location. That's its characteristic.

Mental consciousness is not at the heart center. Rational mind is not there.

Simon - they can't have a location. There is no when or where to life/reality/mind. The mind that is referenced in Mahamudra has none of the qualities of consciousness. Meaning that realization is not an experience or rational explanation or series of experiences or rational explanations.

Why not?

Seriously?

There are many ways to prove that the heart is not the location of the mental consciousness. One such proof is that those who have impaired mental consciousness do not have impaired cardiac function.

Your statement was that the mental consciousness "resides" in the brain.
Is this "mental consciousness" a term that has the same usage as "mental consciousness" when we discuss the 6, 7, or 8 consciousnesses of various Buddhist models? I.e., "Olfactory Consciousness, taste consciousness, tactile consciousness, auditory consciousness, visual consciousness, mental consciousness, etc."

You also stated that this "mental consciousness" is not the consciousness that is "worked with" in Mahamudra meditation. Is that an accurate restatement of your views?

We need to look at what is real past thinking mind. For some there is nothing outside of thinking mind. For others there is life itself. Thinking mind is a small thing. Life is pervasive. When we look at life, without thinking how it should be, then we become aware of it's characteristics. This direct appreciation of the characteristics of life/reality/mind is what counts as realization in Mahamudra.

Mental consciousness in the model you posted is the 6th consciousness. It is what we use when we do formal meditation. It is brain-based. The reality that we want to understand isn't brain-based. When we say that we want to understand the nature of mind we are talking about mind as being pervasive and not brain-based. Mind in this case is no different than life or reality.

In Mahamudra meditation, we work with "mental consciousness." That is true. I don't think positing it as "in the brain" is helpful, though, in the context of Mahamudra practice. Frankly, there are methods of practice which place the mental consciousness, that which we use or work with, in other places....

As for what we are "discovering," Mahamudra terms it "Ordinary Mind," among other terms....Primordial Wisdom, Bare Awareness...etc. You're calling it "life," or "Reality," I guess. But when practicing Mahamudra, we're not initially concerned with locating that, or "examining" it, usually.

To the OP, here's a thought experiment I invented to help me through this at one point.

Locate a particular experience that is in your "mind" (this could either mean experience-at-large, or the more specific mental consciousness, which consists of thoughts, emotions, memories, etc.). Really visualize and pin down where it is "located."

Now, imagine that someone (secretly) removes your brain from the back of your head, and down to your feet so that you don't notice. It's still connected, of course, and don't worry about neural transmission speeds or anything.

Did the location of that experience "move"? If it's really located in the brain, then doesn't that mean it has to move when the brain does?

Of course, it's not very easy to actually do this experiment, but I'll share my conclusion: when the brain moves, no part of experience changes in any way -- which also means that none of it "moved" in any meaningful sense (other than one I have to contrive to maintain my irrational belief that those experiences were "located in" the brain).

The other argument I like to use is this one: it's easy to imagine being in a dream where instead of brains, we have jelly beans in our skulls. Jellyscientists have proven that consciousness is irrefutably caused by jelly beans. Honestly, if I go to a cocktail party in the dream, I may be polite and acknowledge this obvious fact (depending on how cheap the cocktails are, and how many I've gotten down, of course). Same for other practical purposes. But deep down, I know it's all just a bit of fun. There's taking physical materialism seriously, and then there's taking it seriously.

It is the same as trying to pin down whether the chicken or the egg came first. If consciousness is allegedly located in the brain or skull, yet brains and skulls (including your own skull which supposedly contains your own brain) appear to consciousness, then there's no way to make any definitive statements as to what comes first.

And when it comes down to it neither can be found apart from conventionality, so attempting to make a definitive statement regarding either is choosing to be bias about one of two equally unfounded illusions as it is.

But at the same time, I tell you that there is no making an end of suffering & stress without reaching the end of the cosmos. Yet it is just within this fathom-long body, with its perception & intellect, that I declare that there is the cosmos, the origination of the cosmos, the cessation of the cosmos, and the path of practice leading to the cessation of the cosmos."
